Clinical Chemistry

What is clinical chemistry?

Clinical chemistry uses chemical processes to measure levels of chemical components in body fluids. The most common specimens tested in clinical chemistry are blood and urine. Many different tests exist to test for almost any type of chemical component in blood or urine. Components may include blood glucose, electrolytes, enzymes, hormones, lipids (fats), other metabolic substances, and proteins.

The following is a description of some of the most common clinical chemistry tests (used on blood and urine specimens), including some of the uses and indications:

Blood glucose, or blood sugar, levels indicate how the body handles glucose. Measuring glucose levels after fasting (when the patient has not eaten anything for 8 hours) can help diagnose diabetes or hypoglycemia (low blood sugar).
